One person said, “The funny thing, Yang YunSong, SanHe forerunner came from Tang dynasty. There is no evident of the arrangement of LoShu at Tang. A wise speculation, he did not knew LoShu arrangement. As a direct descendant of LoShu, Later Heaven and Earth plate, it does not inherit a feature called four season. Earth plate is "a living fossil". It is derived from LoShu and Later Heaven. TianGan DiZhi respond LoShu arrangement (four season). Four elements divide into Yin part and Yang part, and each part has Heavenly Numeral and Earthly Numeral. This is the basis of Earth Plate. Take an example Summer (Li & Kun Gua). 9 is Li (Yang) and 2 is Kun (Yin). Li is divided into 3 division (Bing Wu Ding) all represent Summer or Fire Element. What is the connection between Najia and 3 Harmony, to LoShu and Later Heaven? Why they divide Earth Plate base on a different thing? LoShu, Later Heaven and Earth Plate, talk at the same frequency, namely four season as macro-cosmos and four element as micro-cosmos. NaJia base on moon phase of Early Heaven, there is no connection between both. My interpretation, based on the above old classic.”

Another person said, “This diagram below posted up by Jay Tee shows how the 24 Mountains (the outer most ring) are made of 8 of the 10 Heavenly Stems (the third ring), 12 earthly Branches (the fourth ring) and 4 of the 8 Trigrams (the fifth ring before the 24 Mountains ring) with the HeTu numbers in the inner two rings.There is nothing special about this diagram, it shows the derivation and the construction of the 24 Mountains. It is not called an Earth Plate by any school, it can be called the 24 Mountain Plate for the want of a name.”​Very confusing indeed…

​THE MAKING OF THE 24 MOUNTAINS

QingNanJing 青囊经 or the Green Satchel Classic as some would call, is believed to have been authored by the legendary Yellow Stone Master or Red Pine Master, even some may also considered him as Great Immortal Huang or Huang DaXian, the patron saint of Divination and the art of the occult largely revered in HongKong. It states the fundamental of FengShui, that is considered a source code for Yang YunSong to write his masterpiece - QingNan AoYou, the Mysterious Saying of the Green Satchel. This classic comprises of three scroll. Upper Scroll prescribed the fundamental of HeTu and LoShu with the prescription of the Early Heaven BaGua arrangement. This is where SanYuan school's fundamentals are enshrined. It also prescribed how the TaiJi turns. Middle Scroll prescribed which part of the Heaven it measures. and how the Heaven YinYang is construed. It is the basis as to how SanYuan define its YinYang. Read HERE for detail. The Lower Scroll prescribed the application where all these come together. It may be a subject for another discussion...

COMMENTARY

It is the will of Heaven to bestow the gifts to Earth revealing the treasures within the humbled Earth. QIAN and KUN, with QIAN the source, KUN the recipient. Yang refers to the male component. Yin refers to the female components. Together it assigns the 10 Heavenly Stem against the HETU configurations. This becomes the basis Grand Master Yang designing the Earth Plate of both SanHe and SanYuan Luopan.

1 odd takes the sign of REN water begins or birth. 6 even takes the sign of GUI water finishes or completes.1&6 same clan of water. 7 odd takes the sign of BING fire finishes or completes. 2 even takes the sign of DING fire begins or birth. 2&7 same way of fire. 3 odd takes the sign of JIA wood begins or birth. 8 even takes the sign of YI wood finishes or completes. 3&8 are friends of wood. 9 odd takes the sign of GENG metal finishes or completes. 4 even takes the sign of XIN metal begins or birth. 4&9 are companions of metal. 5 odd takes the sign of WU earth begins or birth. 10 even takes the sign of JI earth finishes or completes. 5&10 same route of earth.

Shut and open refers to origin and completion. With the 5 elements (signs) this completes the birth and completion of every HETU. - This is the First and Second Ring (HeTu)

Spreading denotes to radiate. Finish is to complete and begin is to undertake. 8 bodies refers to 8 directions. Radiating vastly from the center. Liken to the mother attending to her child, producing nurturing and upbringing completing the cycle of life. Heaven (QIAN) and Earth (KUN) establish its rightful position, one on top of the other as Heaven above, Earth below acknowledging its rightful place in the spectrum of 8 directions in Early Heaven sequence. Mountain (GEN) and Marsh (DUI) connect QI, these GUA has mutually penetrating QI in the spectrum of 8 directions in Early Heaven sequence. Thunder (ZHEN) and Wind (XUN) mutually covering each other in the spectrum of 8 directions in Early Heaven sequence. Water (KAN) and Fire (LI) will not conflict each other in the spectrum of 8 directions in Early Heaven sequence.

These verses established and assigning the 8 GUA to the 8 directions in the sequence of Early Heaven as principle.They are also the actual "Family" grouping in SanYuan DaGua. The so called original "Family". Jiang DaHung borrowed the same notion when he applied such to XuanKong DaGua, which is not accurate. The Later Heaven sequence of the Nine Stars borrowed from the component of JingFang's 8 Palaces BaGua were way too remote as it hasn't been found in the first place. The original SanYuan predates all these...

5 as the center, commanding 5 establishing the 4 cardinals. Commanding and controlling the 4 cardinal directions. With back 1 facing 9 establishing begins and completes as prescribed in the earlier verse. 3,7 occupy sides with the rest establishing a criss and cross arrangement forming net. The net is the operative word. Here it denotes application of the HeTu numerology into a LuoShu arrangement, 1 and 9 has its position facing and backing one another, whereas the rest takes flight to arrange into a net sequence.

This net sequence establish polarities of YIN and YANG, as complementary, containment, producing. Therefore in the LuoShu sequence it also contain the HeTu pairs with YIN YANG mutually producing, complementing and containing. It is the Yang Qi flourish through the vastness of the land, but the Yin Qi that benefits with benevolent, producing. Reading in context of ZhangShu, Yang Qi being external, Yin Qi being internal, matching mutually producing.

Therefore with the LuoShu sequence mapping into the Early Heaven BaGua arrangement, Yang YunSong was able to obtain the LuoShu arrangement, as the forwarding component to the 10 stems. This is not only the fundamental of SanYuan Leaning Star, it is also the Third Ring (Stem)

Heavenly stems depend on elements. Earthly branches relies on seasonal Qi. Water begins from HAI, prosper in ZI and completes in CHOU. Winter QI water reign. Wood begins from YIN, prosper in MAO and completes in CHEN. Spring QI wood reign. Fire begins from SI, prosper in WU and completes in WEI. Summer QI fire reign. Metal begins from SHEN, prosper in YOU and completes in XU. Autumn QI metal reign. These complete the seasonal nodes of the earthly branch giving directions to the LoShu configurations. Adding another layer to the Earth Plate. In ZhangShu, it is noted that Heavenly QI, being external cannot be established. Therefore the QI in every stems cannot be established. Earth QI, being internal established as seasonal nodes can be established. This is the Fourth Ring (Branches).

These speaks of changes in the beginning, where the 8 Heavenly QI from stems matching 12 Earthly QI from the branches, matching with the 4 ordinals GUA make up the 24 subsectors of the BaGua of a Later Heaven arrangement for application. This is the Fifth Ring (Later Heaven BaGua).

CONCLUSION...

There are plenty of craps being taught out there... Some teachers especially in the west teaching this subject, yet they know nuts about basic fundamentals liked how your YinYang turns? How the 24 mountains are constructed? Where does the YinYang Heaven Man Earth Dragons come about? Where are the 3 rings of the SanHe and SanYuan LuoPan? It is very easy to say, the founder of FengShui Qing WuZi or Yang YunSong know nuts about Later Heaven but in truth it is our own handicapped...
